Overview

Rep AI

Rep AI is a sales-focused conversational platform designed specifically for e-commerce merchants who want to provide a concierge-like experience at scale. Instead of waiting for customers to ask questions, you can use behavioral triggers to proactively engage shoppers at critical moments, such as when they linger on a product page or show signs of cart abandonment. The platform uses a proprietary AI engine to understand customer intent and provide accurate product recommendations directly within the chat interface.

You can automate the entire pre-sales journey, from answering technical product questions to handling complex discount inquiries. By connecting directly to your product catalog, the software ensures that every recommendation is based on real-time inventory and pricing. It is built primarily for Shopify merchants and mid-market e-commerce brands looking to increase their conversion rates and reduce the burden on their customer support teams.
